On its age, its old homes and the National Register, Lake Township is more historic than 29% of U.S. towns, #952 of 1,035 in Pennsylvania. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.
Pennsylvania towns list about as much on the Register as the country (a typical Pennsylvania town has 2.1 per 10,000 residents, the U.S. 2.4), so Lake Township’s 0.0 sits below most of its state (25% of Pennsylvania towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
